I don't mind this suggestion at all, even though I think it's use would be incredibly limited this day and age. I'd be interested to see what you'd imagine rules for that sort of section would look like, or if the emphasis would be on moderator discretion.
I'll be candid here. My moderation has been incredibly lax as time has gone on. As the community has become more disconnected to the forums, so has their care for following the rules. Once it got to the point of VA's, HA's, and Directors not following them, I decided to just step back unless it was a serious violation. It seemed to me that top down, no one really cared anymore and my actions would only be viewed as a nuisance, not as protecting good conversations.
Also, while it might look like that, there has been plenty of edits to the community rules and guidelines since 2021, the edit history is just hidden.
